I am going to be installing a Downpipe and a high flow cat soon.

Is there anything I need to know before I do it?

Please list the steps if possible.


Thanks

 

Let the car cool down.

 

its pretty self explanatory... just make sure you have something to take out the O2 sensor... preferably a dog bone style O2 socket or a 7/8 open ended wrench...or both. A hammer and some pb blaster may be a good idea as well

 

If you're putting the car on a lift, its a piece of cake, even I did it

If you're doing it under jack stands its a bit harder but still not bad. The hardest part of any of it is the DP and its not that hard at all. Oh, and also make sure you check for parts of the exhaust that will hang down and strap them down (or up...), it was the smartest thing my friend and I did when we didn mine.

And of course let the car cool down And make sure you have the right gaskets and tools before you get started (including something to take the O2 sensor out like said above)

 

PB Blaster is good stuff

 

Definitely get PB Blaster + air tools(butterfly wrench for tight spots). Otherwise your gonna need a breaker bar with some good leverage (might mean getting the car high). Make sure you have the gaskets. Should be pretty straight forward otherwise...

For the o2 sensor, autozone lets you rent their o2 sensor removers for free (just pay 20 bucks, they refund it when you bring it back).

 

have a buddy come over to give you a hand...its pretty easy

 

I jacked the front and laid it on stands, Did the downpipe. Then lowered it and Jacked the back on stands and did the rest. It sucks to do laying down, have some WD-40 handy (Im not sure what PB blaster is). Some bolts are tiiight

 

the most pain in the you know what is taking off that o2 sensor off the testpipe especially since you have no leverage from underneath the car. Use some pb blaster or wd40.

 

Ya get one of ur buds to come help you and it would make your life alot easier... I did it by myself and it was a pain in the a$$... I just used stacked boards to hold up the old pipes and replaced them and make sure to soak the cat bolts in PB Blaster the night before so it has time to soak in.. GL

 

here is a good place to start http://evomoto.com/index_tech.php?tP...aef8f3a42f1e87

 

Finger tight all the bolts first just to make sure it all lines up. When you go to final tighten the bolts, start at the DP/O2 hsg first. Then do the DP-to-Cat bolts ad finally do the Cat-Catback last. Doing them in this sequence allows you to take up any misalignment in the Catback which is rubber mounted and has bendable flanges.

If you start tightening from the CB first, then any misalignment will be multiplied by the time you get up to the O2 housing and its donut gasket and two bolt flange. It's just easier to fudge any possible mismatch down at the bottom than it is up at the top.

 

PB blaster

 

Good jack stands and a breaker bar comes in handy. Some liquid wrench also helps

 

you need a friend who can help you with it.
First Let the car cool down. because it's veryyy HOT lol
